Task 06: Shared Source Picker

Acceptance

• Reusable workspace-repository, remote-repository, branch, and folder selection leaves live under components/workspace-source-picker/ with task-create behavior unchanged.
• Mixed source form state supports independent stable rows, validation, retry, and exact HTTP payload construction for repository, remote repository, and folder kinds.
• Executor capability hides the folder row kind for Docker, SSH, Sprites, and remote Docker while leaving local and remote repository choices available.
• Frontend API/types/store contracts model workspace folders and attachment responses, and the old Worktree-only multi-repository guard is removed only after runtime capability is present.

Verification

cd apps/web
rtk pnpm test -- components/workspace-source-picker components/task-create-dialog lib/api/domains/kanban-api
rtk pnpm run typecheck

Dependencies

Task 02 for the final request contract. This task may begin extraction in parallel with Tasks 03/04 but must not delete the executor guard until Task 05 is integrated.

Inputs

• Existing task-create picker files named above.
• Spec: mixed batch inputs and executor parity.

Output contract

Summary, files changed, tests run, blockers, risks, divergence, and task/plan status updates.

Completion notes

• Added the shared typed source-row state, validation, deterministic request builder, and executor capability helper under apps/web/components/workspace-source-picker/.
• Re-exported the existing task-create repository, remote repository, branch, and folder picker leaves from the shared namespace without changing their behavior. Task 07 owns the Add sources desktop/dialog/drawer compositions.
• Mobile parity handoff: Task 07 must consume this same state/capability layer in a phone-native, viewport-contained MobilePickerSheet or Drawer with a single internal scroll owner and 44px touch controls; this task introduces no rendered outer surface, so no mobile E2E is appropriate yet.
• Kept the existing Worktree-only multi-repository guard in task-create-dialog-computed.ts and task-create-dialog-multi-repo-guard.ts. Deferred handoff to Task 05: remove or relax that create-task guard only after Task 05 wires the remote runtime multi-repository capability and its executor profile contract; this attachment-picker capability does not make create-task provisioning safe by itself.
